Leandra Medine of The Man Repeller, after Chanel, Paris, October 2015. 
Love a pinafore dress! And this colour combination is so fresh and lovely. 
Recreate Leandra's look (kind of):
N Nicholas Belted frayed-denim pinafore dress, Milly Wool Tuck jumper, Topshop Unique Inverness wool-blend mini dress, ASOS Pinafore dress, or Kate Spade New York bow tie crepe a-line dress
